Windows - WSL¶
An alternative for running openCFS on Windows is the usage of WSL. It lets one run a Linux environment on Windows without the overhead of a VM, or dual-boot setup.
For the installation, please follow the provided guide Manual-WSL-Installation. It is recommended to use the Ubuntu distribution, since this is tested, but it should run on all distribution.
After the installation of WSL and the distribution the Linux guide on installing openCFS can be followed.
Please note that it could be necessary to change the permissions of the cfs folder. This can be done with
sudo chmod -R 755 /cfs_dir.
It is possible that a shared library is missing from within the ubunut WSL (
libgomp.so.1). It can be installed with
sudo apt install libgomp1
Afterwards it is possible to call openCFS from within powershell via
wsl bash -c -i cfs --help
To get GUI applications running in WSL, one can use XLaunch. For further details, there are different tutorials like 1, 2.
